Looks like you''re using Lua 4.0. I strongly suggest you upgrade.

Anyways, no, you don''t need a different lua_State.

What in the code made you think I had version 4?

lua_dofile() is not often used in Lua 5.0; it''s mostly maintained for compatibility.

Will it load the functions and global variables and all else?

Yeah.

What you have to understand about Lua, is that it only does stuff by executing. Consider a file containing the lua code:

function foo(i)
return i+1
end

Now, what that code ACTUALLY does is something like this:

foo = function(i) return i+1 end

In other words, when executed, it sets the global variable foo to a function, with the provided body.

Think of each lua script file like a big function. It does its thing (usually registering functions), and then returns. If you use lua_dofile() multiple times, it''s like running each function in turn. All of the effects of each function are kept around.

luaL_loadfile() loads the file into a function (which it places at the top of the stack), but does not call it. You can then call it yourself (usually with lua_call(L, 0, 0)), or save it for execution later.
